From Faro:
Go on the A22(Via do Infante) highway, exit on the V.R.St.António exit, get on the IC 27 towards Alcoutim, after passing by Odeleite turn left (Vale do Perreiro) continue straight forward for about 26 km, passing by Vaqueiros towards Martimlongo.
The mining Park has a plaque by the main road(EM 506), just follow that plaque.
